Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

Australia introduces its first exhaust rule but makes all the mistakes the US did

Baua Electric

Australia doesn’t have its own fuel efficiency standards, making it one of only two advanced countries without such a rule, alongside Russia. The US EPA has long had what is referred to as a “ footprint rule, ” which allows larger vehicles to pollute more. If that sounds familiar, it’s because it is.

Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

On the other hand, however, the lower exhaust gas temperatures result in a lack of energy for their propulsion on the exhaust side. Their approach was to keep the level of raw emissions low by means of extremely lean and therefore colder combustion, making it possible to dispense with an exhaust aftertreatment system.
